Great singletrack, some short steep climbs, can be slippery, rutty and messy in early spring. Gets overgrown with blackberry during peak summer. Also open to hikers, so watch for peeps! Approx. 1 1/2 - 2 hours ride time for intermediate riders when conditions are good, can be 3 or more when wet. A nice roller that will get your heart pumping, a good ride and a workout.
From Portland take the 26 West to the 217 South to the 8 West. Continue to the 47, turn left towards Henry Hagg Lake. Follow the signs. $5 / day or $50 / year. Once through the gate, turn left at West Shore Drive. Park in the big lot. Head around clockwise to the first trailhead red post on your right and drop in!
